Salt Creek Ammunition has vintager type shells in bismuth only as near as I can tell. I have some of their 10 ga. shells which are supposed to be in the 6500 psi range. I haven't used them as yet so your mileage may vary.

Also, Buffalo Arms seems to carry several black powder loadings if that fits the bill for you.
